My iPhone 4S won't connect to wifi
So 2 days ago I noticed that my phone was running on 3G rather than my home wifi, i check it and the button won't even slide over. I took it to Verizon and they gave me a few suggestions none of which worked, so on Friday I'm planning to go to the Apple store. Do I have to make an appointment with the genius bar? and What will the apple store do to help me?
iPhone 4S, iOS 7.0.4
